Koenigsegg also managed to keep the car's weight down to 1,360 kg, which meant that the car has a 1 hp/kg power to weight ratio, which explains the One:1 type name.

Based on the 'regular' production Agera, which itself was a gradual evolution of its predecessors, the One:1 is powered by a bespoke, all-aluminium, twin-turbo V8. Like the earlier Koenigsegg engines, the One:1's V8 could run on E85, regular pump gasoline and race fuel. In addition to pumping out around 1,360 hp, it was also good for a maximum torque of 1,371 Nm. All this power was transferred to the rear wheels through a seven-speed, dual-clutch gearbox.

Exotic materials were used throughout the One:1 to keep the weight down to the absolute minimum. It was built around carbon-fibre composite monocoque and the same material was used for the bodywork. The composite components were built in-house, in Koenigsegg's own factory. Many of the metal components were either crafted from aluminium alloys or titanium. The fully active suspension used double wishbones with carbon-fibre springs on all four corners.

The wheels were crafted in-house, completely from carbon-fibre to make sure they were both as light as possible to lower the un-sprung and were also capable of speeds of of well over 400 km/h. A proprietary technology was used to make the centre section of the wheel and the spokes hollow. Compared to similar aluminium wheels, the carbon-fibre ones are around 40% lighter. Perfectly moulded, the wheels only needed a polish once they were completed. Page 1 of 2 Next >>
